帮同事看的，顺便记录一下。
寻找路由
反序列化处理出传入的json没啥跟进的，直接看UploadingFileInfo，有啥就可以定义啥
主要跟函数UploadingFileInfo
完整函数如下：
public string StoreFileAdvanced(UploadingFileInfo<string> fileUploadInfo, Stream fileStream){string result = "";string str = "_temp";string str2 = string.Format("{0}_{1}_{2}", fileUploadInfo.UploadUserNo, string.Format("{0:yyyyMMddHHmmssffff}", fileUploadInfo.UploadTime), fileUploadInfo.FileName + str);if (!Directory.Exists(FileUploadHelper.UploadFileFolder)){Directory.CreateDirectory(FileUploadHelper.UploadFileFolder);}using (FileStream fileStream2 = File.Open(FileUploadHelper.UploadFileFolder + Path.DirectorySeparatorChar.ToString() + str2, FileMode.Append)){this.SaveFile(fileStream, fileStream2);fileStream2.Close();}string uploadFileFolder = FileUploadHelper.UploadFileFolder;string text;if (fileUploadInfo.IsUseMongdb){text = string.Format("{0}_{1}_{2}", fileUploadInfo.UploadUserNo, string.Format("{0:yyyyMMddHHmmssffff}", fileUploadInfo.UploadTime), fileUploadInfo.FileName);}else{text = fileUploadInfo.FileName;if (!Directory.Exists(uploadFileFolder)){Directory.CreateDirectory(uploadFileFolder);}if (File.Exists(uploadFileFolder + Path.DirectorySeparatorChar.ToString() + text)){File.Delete(uploadFileFolder + Path.DirectorySeparatorChar.ToString() + text);}}if (fileUploadInfo.LastChunk){File.Move(FileUploadHelper.UploadFileFolder + Path.DirectorySeparatorChar.ToString() + str2, uploadFileFolder + Path.DirectorySeparatorChar.ToString() + text);UploadResult uploadResult = new FileUploadHelper().UploadFinished(new UploadFileInfo{FileName = fileUploadInfo.FileName,FilePath = string.Format("{0}{1}{2}", FileUploadHelper.UploadFileFolder, Path.DirectorySeparatorChar, text),Parameters = fileUploadInfo.ExtendInfo,UniqueKey = fileUploadInfo.UniqueKey,UploadMethodName = fileUploadInfo.UploadMethodName,UserNo = fileUploadInfo.UploadUserNo,IsUseMongdb = fileUploadInfo.IsUseMongdb,IsUseCloud = fileUploadInfo.IsUseCloud,CloudPath = fileUploadInfo.CloudPath,Size = fileStream.Length});result = uploadResult.ID;if (uploadResult != null && !string.IsNullOrEmpty(uploadResult.sErrInfo)){throw new Exception(uploadResult.sErrInfo);}}return result;}
通过上述代码可以看到需要UploadUserNo、LastChunk、FileName、IsUseMongdb、UploadTime
其中
if (fileUploadInfo.IsUseMongdb){text = string.Format("{0}_{1}_{2}", fileUploadInfo.UploadUserNo, string.Format("{0:yyyyMMddHHmmssffff}", fileUploadInfo.UploadTime), fileUploadInfo.FileName);}else{text = fileUploadInfo.FileName;if (!Directory.Exists(uploadFileFolder)){Directory.CreateDirectory(uploadFileFolder);}if (File.Exists(uploadFileFolder + Path.DirectorySeparatorChar.ToString() + text)){File.Delete(uploadFileFolder + Path.DirectorySeparatorChar.ToString() + text);}}
构造对应请求即可实现文件上传
